Executing command after missing executable ""

Answer 1

As I read the documentation, you are expected to provide an executable command. A .bat file is not executable which would explain why your command fails.

Prepend your command with cmd.exe /c to provide the executable which processes the .bat file.

cmd.exe /c "G:\Lazarus project\dll test\copy.bat"
